RESUMEN
OBJECTIVES: Cerebral amyloid angiopathy (CAA)-related features on neuroimaging often coexist with signs of arteriolosclerosis-small vessel disease on neuroimaging in people with intracranial hemorrhage (ICH). This study aimed at defining the value of amyloid pathology detected by 18Fflutemetamol PET in reclassification and stratification of risk of bleeding in people with mixed CAA-arteriolosclerosis features. METHODS: We included consecutive patients admitted to 2 institutions (2018-2023) with spontaneous symptomatic ICH, subarachnoid hemorrhage (SAH), transient focal neurologic episodes (TFNE), or cognitive impairment and MRI showing CAA hallmarks. All patients underwent brain magnetic resonance imaging (MRI) with susceptibility weighted imaging and 18Fflutemetamol PET imaging and were followed up for at least 1 year. We compared cases with CAA and arteriolosclerosis + CAA features and defined long-term outcomes (composite outcome including death, ICH, ischemic stroke, SAH, TFNE) depending on PET status (CAA/amyloid pathology vs arteriolosclerosis-predominant groups). RESULTS: Among 47 patients, according to PET and MRI imaging, 38 patients were reclassified in the CAA/amyloid pathology group and 9 in the arteriolosclerosis-predominant group, with similar cardiovascular risk factors but a significantly higher lobar microbleed burden for the former group. The CAA/amyloid pathology group had higher rates of composite outcome (43.9 vs 11.1 events per 100 patient-year; p = 0.039) and ICH (36.5 vs 5.6 events per 100 patient-years; p = 0.04) compared with the arteriolosclerosis-predominant group. DISCUSSION: 18FFlutemetamol PET imaging can help in reclassification of mixed arteriolosclerosis + CAA into CAA/amyloid pathology and arteriolosclerosis-predominant, with implications on long-term risk of recurrent events. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that 18Fflutemetamol PET can distinguish between CAA + arteriolosclerosis and arteriolosclerosis-predominant pathology.

OBJECTIVE: The COVID-19 pandemic had a profound negative impact on the psychological wellbeing of healthcare providers (HPs), but little is known about the factors that positively predict mental health of primary care staff during these dire situations. METHODS: We conducted an online questionnaire survey among 702 emergency department workers across 10 hospitals in Switzerland and Belgium following the first COVID-19 wave in 2020, to explore their psychological vulnerability, perceived concerns, self-reported impact and level of pandemic workplace preparedness. Participants included physicians, nurses, psychologists and nondirect care employees (administrative staff). We tested for predictors of psychological vulnerability through both an exploratory cross-correlation with rigorous correction for multiple comparisons and model-based path modelling. RESULTS: Findings showed that the self-reported impact of COVID-19 at work, concerns about contracting COVID-19 at work, and a lack of personal protective equipment were strong positive predictors of Depression, Anxiety, and Stress, and low Resilience. Instead, knowledge of the degree of preparedness of the hospital/department, especially in the presence of a predetermined contingency plan for an epidemic and training sessions about protective measures, showed the opposite effect, and were associated with lower psychological vulnerability. All effects were confirmed after accounting for confounding factors related to gender, age, geographical location and the role played by HPs in the hospital/department. CONCLUSIONS: Difficult working conditions during the pandemic had a major impact on the psychological wellbeing of emergency department HPs, but this effect might have been lessened if they had been informed about adequate measures for minimizing the risk of exposure.

Neurodevelopmental disorders are a group of complex conditions with onset in the developmental period, that produce impairments of global functioning. For these features, the rehabilitative approaches should be flexible, tailored to the individual characteristics of each patient, and characterized by a standardized multidimensional view, for taking into consideration all the several areas of neurodevelopment. This single-arm clinical trial aims to investigate the features, feasibility, and limitations of Neuro-Psychomotor (NPM) intervention, an Italian naturalistic model for children with Neurodevelopmental Disorders. 30 children (16 with Mixed Specific Developmental Disorder vs 14 with Intellectual Disability) were recruited and their parents filled out two validated tools questionnaires (Developmental Profile-3 and Sensory Processing Measure), before and after 6 months of NPM intervention. Although with some limitations, findings showed that NPM intervention is reliable, flexible, and helpful for children with different neurodevelopmental disorders. Further studies are necessary to investigate its efficacy on a larger sample.
RESUMEN
BACKGROUND AND PURPOSE: Iatrogenic cerebral amyloid angiopathy (iCAA) is a specific type of cerebral amyloid angiopathy which is becoming increasingly diagnosed. It has been hypothesized that iCAA might arise as a late consequence of past neurosurgical interventions involving dural patch grafts. Positron emission tomography (PET) scans with amyloid tracers and the assay of beta-amyloid levels in cerebrospinal fluid (CSF) are auxiliary criteria, however, definite diagnosis remains histopathologically determined. METHODS: Case report. RESULTS: We present a 48-year-old patient who suffered multiple lobar cerebral haemorrhages from the age of 47. The patient had undergone surgery for remolval of hemangioblastoma with lyophilized dural graft at the age of 11, in 1987. Brain MRI, amiloid PET and CSF analysis led to a diagnosis of probable iCAA. CONCLUSION: It is necessary to increase the awareness of iCAA, in order to avoid overlooking the potential causal involvement of surgical procedures which took place far back in time. Moreover, the diagnostic relevance of amyloid PET and beta-amyloid levels in CSF must be emphasised.

Emerging evidence indicates that the etiologic agent responsible for coronavirus disease 2019 (COVID-19), can cause neurological complications. COVID-19 may induce cognitive impairment through multiple mechanisms. The aim of the present study was to describe the possible neuropsychological and metabolic neuroimaging consequences of COVID-19 12 months after patients' hospital discharge. We retrospectively recruited 7 patients (age [mean ± SD] = 56 years ± 12.39, 4 men) who had been hospitalized for COVID-19 with persistent neuropsychological deficits 12 months after hospital discharge. All patients underwent cognitive assessment and brain (18F-FDG) PET/CT, and one also underwent 18F-amyloid PET/CT. Of the seven patients studied, four had normal glucose metabolism in the brain. Three patients showed various brain hypometabolism patterns: (1) unilateral left temporal mesial area hypometabolism; (2) pontine involvement; and (3) bilateral prefrontal area abnormalities with asymmetric parietal impairment. The patient who showed the most widespread glucose hypometabolism in the brain underwent an 18F-amyloid PET/CT to assess the presence of Aß plaques. This examination showed significant Aß deposition in the superior and middle frontal cortex, and in the posterior cingulate cortex extending mildly in the rostral and caudal anterior cingulate areas. Although some other reports have already suggested that brain hypometabolism may be associated with cognitive impairment at shorter intervals from SarsCov-2 infection, our study is the first to assess cognitive functions, brain metabolic activity and in a patient also amyloid PET one year after COVID-19, demonstrating that cerebral effects of COVID-19 can largely outlast the acute phase of the disease and even be followed by amyloid deposition.

Sensory Processing Disorders (SPDs) define dysfunctions in modulating, organising, and using information from several sensory channels for regulating motor, behavioural, emotional and attention responses. Although SPD can be identified also as an isolated condition in young children, its presence in Autism Spectrum Disorder (ASD) population is really frequent. The study purpose is to explore the SPD clinical expression and the putative correlation with several behavioural aspects both in children with ASD and in those with isolated SPD. Therefore, 43 preschool-aged children (25 ASD vs. 18 SPD) were recruited, and their parents completed three questionnaires (Developmental Profile-3, Sensory Processing Measure-Preschool, Repetitive Behaviour Scale-Revised) to evaluate behavioural alterations and developmental levels. The main result is that both ASD and SPD groups had significantly sensory-related behavioural symptoms, although ASD children seem to be more impaired in all areas. Several significant correlations were found between sensory processing difficulties and repetitive behaviours, but in the SPD group a specific relationship between Body Awareness and Ritualistic/Sameness Behaviour was found. Conversely, in the ASD group, more diffuse interlinks between sensory processing difficulties and motor behaviours were significant. In conclusion, the present study confirms the key role of sensory-motor skills in early diagnosis and intervention among children at risk for neurodevelopmental disorders.
RESUMEN
BACKGROUND AND PURPOSE: Cognitive dysfunction has been observed following recovery from COVID-19. To the best of our knowledge, however, no study has assessed the progression of cognitive impairment after 1 year. The aim was to assess cognitive functioning at 1 year from hospital discharge, and eventual associations with specific clinical variables. METHODS: Seventy-six patients (aged 22-74 years) who had been hospitalized for COVID-19 were recruited. Patients received neuropsychological assessments at 5 (n = 76) and 12 months (n = 53) from hospital discharge. RESULTS: Over half (63.2%) of the patients had deficits in at least one test at 5 months. Compared to the assessment at 5 months, verbal memory, attention and processing speed improved significantly after 1 year (all p < 0.05), whereas visuospatial memory did not (all p > 0.500). The most affected domains after 1 year were processing speed (28.3%) and long-term visuospatial (18.1%) and verbal (15.1%) memory. Lower PaO2 /FiO2 ratios in the acute phase were associated with worse verbal long-term memory (p = 0.029) and visuospatial learning (p = 0.041) at 5 months. Worse visuospatial long-term memory at 5 months was associated with hyposmia (p = 0.020) and dysgeusia (p = 0.037). CONCLUSION: Our study expands the results from previous studies showing that cognitive impairment can still be observed after 1 year. Patients with severe COVID-19 should receive periodic cognitive follow-up evaluations, as cognitive deficits in recovered patients could have social and occupational implications.

Sensory processing abilities play important roles in child learning, behavioural and emotional regulation, and motor development. Moreover, it was widely demonstrated that numerous children with neurodevelopmental disabilities show differences in sensory processing abilities and self-regulation compared with those of typical children. For these reasons, a complete evaluation of early symptoms is very important, and specific tools are necessary to better understand and recognize these difficulties during childhood. The main aim of this study was to translate, culturally adapt, and validate in a population of Italian typically developing (TD) children the Sensory Processing and Self-Regulation Checklist (SPSRC), a 130-item caregiver-reported checklist, covering children's sensory processing and self-regulation performance in daily life. Preliminary testing of the SPSRC-IT was carried out in a sample of 312 TD children and 30 children with various developmental disabilities. The findings showed that the SPSRC-IT had high internal consistency, a good discriminant, and structural and criterion validity about the sensory processing and self-regulation abilities of children with and without disabilities. These data provide initial evidence on the reliability and validity of SPSRC-IT, and the information obtained by using the SPSRC-IT may be considered a starting point to widen the current understanding of sensory processing difficulties among children.
RESUMEN
Due to its complexity and high variability in symptomology, autism spectrum disorder (ASD) requires a coordinated and multidisciplinary intervention to better support the different programs over time and to promote social interactions in all contexts of life. Telemedicine can offer a valuable contribution in this regard, providing low-cost and portable applications. In this paper, we presented an Italian project, SUPER, which aimed to foster collaboration and information sharing between ASD families, health services, and schools. SUPER provided a digital platform with several tools that were useful both to enhance general and specific ASD knowledge and to promote personalized programs for children with ASD. We conducted a preliminary user test for the platform with 30 participants (18 therapists and 12 parents of children with ASD) using the system usability scale (SUS). The total mean SUS score (89.2) showed that SUPER is an excellent, usable system. Moreover, we extracted the usability and learnability mean components from the SUS scores, which were 96.1 and 61.7, respectively. Our preliminary results indicate that SUPER is a very user-friendly application and its innovative telemedicine approach could be ahelpful communication and collaboration tool among the different contexts of care for children with ASD.
RESUMEN
Caregivers of children with neurodevelopmental disorders play a central role during the rehabilitation and education processes, but they have an increasing risk of psychosocial problems even if the literature is not so agreed upon the specific and predisposing factors to that. The aim of this study was to examine possibly differences of burden levels in an Italian sample of principal caregivers of children with different kinds of neurodevelopmental disorders and to investigate the possible links between some clinical and sociodemographic variables and the levels of caregiver's burden. 105 caregivers of school-aged children with neurodevelopmental disorders were included in the study and completed three online questionnaires (General Questionnaire, Caregiver Burden Inventory, Zarit Caregiver Burden Scale). Results highlighted that about the half of caregivers show from moderate to high levels of stress, but parents of children with Autism Spectrum Disorder and Intellectual Disability show greater difficulties than parents of children with Attention-Deficit Hyperactivity Disorder, Language and/or Learning Disorder, and Developmental Coordination Disorder. Moreover, it was evident a negative correlation between the burden levels and the age of children, but also a direct correlation between the burden levels and the weekly hours of rehabilitation. These findings show that severity of caregiver's burden is dependent by the type of neurodevelopmental disorder and suggest that an ecological and family-centred approach is necessary to guarantee the life health developmental course of these children.
RESUMEN
INTRODUCTION: The most accurate way of assessing kidney function is the measurement of the glomerular filtration rate (GFR). Since, we do not have good formulae to estimate GFR in elderly, in this study we evaluate the accuracy of the most commonly used formulas for the estimation of GFR in comparison with direct measurement in elderly. MATERIALS AND METHODS: 85 patients (51 males and 34 females), with an average age of 76.2 ± 4.4 years, 42% already diagnosed with chronic kidney disease (CKD) were investigated. Two plasma samples were collected between 60-90 and 165-195 minutes after injection of 99mTc-DTPA, and the GFR was calculated applying Charles D. Russell's two-sample method. RESULTS: When comparing the GFR values obtained from the various formulae by creatinine levels with the GFR values obtained by measuring 99mTc-DTPA residue, the following concordance values emerged: (1) MDRD: 57.5 ± 9.59 %; (2) Cockroft-Gault: 48.33 ± 24.93; (3) CKD-EPI: 49.40 ± 26.30; (4) BIS1: 58 ± 6.79. CONCLUSION: Our data shows a greater concordance between the GFR values calculated with the Russell's method and the estimated values of GFR when the latter are calculated using the MDRD or BIS1 formulae.

Since the beginning of second decade of last century, when it was introduced in many oncologic scenarios, immunotherapy has become an important tool in the management of a growing number of cancers. Immunotherapy for cancer appears to be useful, improving not only progression free survival but also overall survival, thus achieving the goal that many advanced cancers, previously considered without effective treatment options, have now become successfully treatable. However, considering the relatively recent introduction of these drugs in clinical scenarios and the continuous release of new drugs, there is a lack of large validated clinical experiences and many issues are today debated amongst which the evaluation of the response to immune-therapy. Engaging the host immune system in fighting against cancer is an energy-consuming process, requiring T-cell recruiting; this process, named "pseudo-progression," sometimes produces an increase of both dimensional and metabolic ratio of the lesions, as well as the appearance of "new lesions." This behavior, always considered as undisputed progressive disease when traditional chemotherapy is employed, should be carefully considered in the field of immunotherapy, where the phenomenon of "flare" followed by regression of the disease can occur. In this paper, Authors analyzed the best available evidence in this field, reviewed the most important issues concerning the development of immunotherapy, and addressed evidence and concerns about the evaluation of response when using immunotherapy drugs, in terms of both radiological and nuclear medicine criteria.

Società Scientifiche Italiane Insieme per gli Adolescenti con Malattie Onco-ematologiche (SIAMO) is an Italian nationwide scheme that focuses on adolescent patients with cancer. Some of its activities include promoting dedicated local projects at the various oncology centers all over the country and organizing events to improve awareness regarding cancer in adolescence. It is with these aims in mind that it organized the Winners' Cup, a football tournament between Italian adolescents who had (or had had) pediatric cancers. There were 144 young people 15 to 24 years old who arrived from 16 different treatment centers around the country to take part in the tournament and share their stories. Such an event had never been attempted before, in Italy at least. The Winners' Cup was a great success and an opportunity to focus attention on the particular clinical, psychological, and social needs of cancer patients in this age group.

Positron emission tomography (PET) using 18F-fluorodeoxyglucose (18F-FDG) is useful for staging non-small cell lung cancer (NSCLC), decide the appropriate initial management, and evaluate the response to therapy. Metastatic spreading is very common during the course of NSCLC and principal localization sites include: regional and mediastinal lymph nodes and organs such as the contralateral lung parenchyma, bone, brain, adrenal gland, pleura, and liver. Myocardial localizations are very rare, often asymptomatic, and difficult to diagnose. For this reason, only a few cases are reported in the literature. Here, we report a case of an asymptomatic patient affected by locally advanced NSCLC and high metabolic lesion of the interventricular septum.
RESUMEN
OBJECTIVE: the purpose of this study was to offer an example of evaluations of the ISO9001 certified internal quality assurance (QA) system of 99mTc-radiopharmaceutical preparations and quality control in vivo use, using industrial kits and generators in order to identify possible sources of errors in the procedures labeling and quality control procedures. METHODS: The study was performed at a single institution over a period of three years (July 1st, 2011 - July 1st, 2014), and included a total of 2280 radiopharmaceutical preparations prepared by four different technologists. All the radiopharmaceutical preparations and quality controls were performed according to each SPC provided by the manufacturer. The radiopharmaceutical preparations were the following (trade names are reported in brackets): 99mTc-albumin colloid [Nanocoll] (n=349), 99mTc-oxidronate [Technescan®hdp] (n=701), 99mTc-exametazime [Ceretec] (n=169), 99mTc-sestamibi [Cardiolite] (n=92), 99mTc-albumin aggregated [Technescan®lyomaa] (n=140), 99mTc-tetrofosmin [Myoview]) (n=567), 99mTc-diethylene triamine pentacetic acid [Technescan®dtpa] (n=254), and 99mTc-dimercapto succinic acid [Renocis®] (n=8). Data were analyzed to determine the number and type of radiopharmaceutical labelling failure and to derive the sources of these failures to define corrective actions and optimize the quality assurance program. RESULTS: A total of 2280 procedures were performed and recorded. Following the quality control procedure six out of the 2280 preparations (0.26%) were non-conforming for clinical use with the RCP limits indicated in the SPC. Five of these were due to gross technical errors in measurements and manual procedures and were immediately repeated, returning within the limits of acceptability. The sixth failure was due to short incubation time, though compliant with the manufacturer's instructions. CONCLUSIONS: We concluded that the quality of the final product depends on a controlled production system based on the implementation of specific standard operating procedures (ISO9001, SOP) for each radiopharmaceutical production, according to strict adherence to the SPC of each radiopharmaceutical. Based on these conclusions, in our opinion every quality control suggesting a possible error in the synthesis procedure recommended in the SPC should be immediately reported to the manufacturer, for a revision of the SPC, as well as to the regulatory agencies for an alert. This strategy may in fact allow the continuous improvement of the labelling procedures and therefore the optimization of the quality control procedures frequency to ensure both patients safety and a more rational management of resources for economic sustainability.

Urinary clearance of F-FDG and variability in bladder wall FDG uptake may hamper the interpretation and limit the use of FDG-PET/CT for imaging bladder tumors. Nevertheless, careful combined evaluation of both CT and FDG-PET images of the urinary tract can provide useful findings. We present 2 cases of bladder cancer detected by FDG-PET/CT. These cases suggest that FDG uptake can be indicative of malignancy in bladder cancer when viewed in conjunction with CT scans and that whole-body FDG-PET/CT scans should always be reviewed with particular attention to the urinary tract because abnormalities suggestive of bladder cancer can be found unexpectedly.

A mindful approach to education and training could improve students' reflective capacities and have positive effects on clinical practice because it facilitates a helping relationship. The main aims of this study were to investigate whether participation in a mindful-based University training was associated with increases in mindfulness skills as measured by the 5-Facet M Questionnaire, and to present the Italian validation of the questionnaire. Sixty-seven students from the course Neuro and Psychomotor Therapy were enrolled. They filled in the self-administered 5-Facet M Questionnaire before and 1 month after a mindfulness-based training, focused on role-playing and followed by a feedback group discussion. The Italian version of the 5-Facet M Questionnaire had good psychometric properties. The pre- and post-training analysis showed a significant increase in the subscale 'Observing'. Findings suggest that role-playing and feedback group sessions are valid tools to improve students' mindfulness skills.

In Switzerland, a fifth of people with HIV are unaware of their status and 50 % are diagnosed late (< 350 CD4 / µl). Yet, in the years prior to diagnosis, these patients have often presented to the emergency department (ED) with problems related, or not, to HIV infection, presenting missed opportunities for earlier diagnosis. The current FOPH recommendations assume that doctors can recognise HIV indicator diseases, and patients from high-risk groups, and offer an HIV test (targeted screening). Studies conducted at Lausanne University Hospital ED report that most doctors are unfamiliar with the FOPH recommendations and that HIV screening occurs in only 1 % of patients seen. This review discusses the logic of non-targeted screening in the context of the UNAIDS 2016-2021 strategy to end the AIDS epidemic by 2030.
En Suisse, un séropositif sur cinq ignore son statut VIH+ et un sur deux est diagnostiqué à un stade tardif (< 350 CD4 / µl). Dans les années précédant leur diagnostic, ces patients ont souvent consulté une ou plusieurs fois aux urgences pour des plaintes liées ou non à l'infection VIH, ce qui constitue des opportunités diagnostiques manquées. Les directives actuelles de l'Office fédéral de la santé publique (OFSP) reposent sur la capacité du médecin à reconnaître une maladie indicatrice du VIH ou l'appartenance d'un groupe à risques pour initier un dépistage (dépistage ciblé). Les études menées aux urgences du CHUV montrent que cette politique est méconnue et n'aboutit à un dépistage que pour seulement 1 % des consultations. L'article explore le rationnel d'une stratégie de dépistage non ciblé pour espérer éradiquer cette épidémie en 2030, comme énoncé dans le plan d'ONUSIDA.
